I wrote a shared-variable interface which uses the BSD socket stuff
underneath.  It was designed to do exactly the stuff you describe.
It was written up in the USENIX Winter '85 proceedings.  If you are
interested, you can ftp it from durer.cme.nist.gov.  Retrieve the
directory ~ftp/pub/cm.  The paper is included along with lots of
examples.

Even if you don't use it, the code includes a nice library for making
client/server modules a snap.  All public-domain.
